Which tires to replace original TE 225/75/R15/C

Thanks PartyMarty. Prior to this thread I had absolutely no idea that the ST tires were manufactured with so much less testing. And I wonder if many people really realize this. I sure didn't. When I saw how little they were tested and the main fact being that by "trailer" use that in effect sorta meant they were not being certified to haul "humans". That sure amazed me, and I can't thank the folks here enough.
